Problems solved by technology

[0003] Because sweet potatoes have strict requirements on temperature and humidity during storage, mildew is prone to occur if they are not careful, causing economic losses to growers. The existing technology mostly uses the lime powder method for storage in the cellar. However, lime powder heats up after absorbing water, which is easy to cause environmental pollution Temperature fluctuations are not conducive to the storage of sweet potatoes, causing mildew and rot during storage

Embodiment Construction

[0012] The overwintering storage method of sweet potato is characterized in that comprising the following steps:

[0013] (1) Preparation before storage: build a storage room, use the cellar storage method, and use 50% carbendazim wettable powder 1500 times liquid to fully disinfect the cellar before storage, and prepare coarse river sand, plant ash, and rice straw. After sterilizing the rough river sand and rice straw with 50% carbendazim wettable powder 1500 times liquid, expose to the sun for 7-10 days, prepare temperature measuring equipment and humidity measuring equipment, and remove mildew and rot in sweet potatoes that need to be stored individual, put it in a ventilated place to dry for 5-8 days;

[0014] (2) Storage: When storing, lay coarse river sand on the bottom of the cellar with a thickness of 10-15cm, rice straw on the coarse river sand with a thickness of 5-6cm, plant ash on the rice straw with a thickness of 2-3cm, and place sweet potatoes On the plant ash,...

Abstract

The invention discloses a method for storing sweet potatoes through the winter. Because requirements for temperature and humidity are strict in the storage process of sweet potatoes, sweet potatoes get mildewed easily due to any carelessness, and economic losses are brought to growers. In the prior art, most sweet potatoes are stored by adopting a cellar lime powder method; however, lime powder emits heat after absorbing water, environment temperature fluctuation is caused easily, sweet potato storage is not facilitated, and sweet potatoes get mildewed and rotted in the storage process. Sweet potatoes stored according to the method are unlikely to get mildewed and are high in freshness.

Description

technical field [0001] The invention relates to the field of agricultural product storage, in particular to a winter storage method for sweet potatoes. Background technique [0002] Sweet potato is the main food crop in my country. It has high calorie content and is rich in vitamins, minerals and cellulose. Now sweet potato is widely recognized as a good health product. In recent years, the planting area of ​​sweet potato in my country has risen steadily. Among them, safe storage is an important link to ensure production. [0003] Because sweet potatoes have strict requirements on temperature and humidity during storage, mildew is prone to occur if they are not careful, causing economic losses to growers. The existing technology mostly uses the lime powder method for storage in the cellar. However, lime powder heats up after absorbing water, which is easy to cause environmental pollution Temperature fluctuations are not conducive to the storage of sweet potatoes, causing mil...
